A the friction member are held in tact by means er the spider spring l0 locked out with more particularity the essential elements of novelty in the appended claims.

lin the dravvings- Figure l, is a side elevation of a shock absorber or the friction type illustrating the employment of invention in connection therewith,

Fig. 2 is a plan view of my improved form of connection; and

l? ,1,1 3 a section taken of Q"ig. 2.

Referring new to the drawings in detail in which like characters of reference are employed. to designate similar parts through out the several views, 7 and 8 represent the supporting arms of a shock absorber of the friction type, these arms terminating in enlarged annular portions between 4which are 'positioned a plurality of disks or plates torming the :friction member 9. The parts of constant conin position by the .nut ll, an indicator being provided, as shown at i2, to permit of the adjustment of the spring to the tension desired. All of the parts just described do not forni a part of my 'present invention, and hence it is unnecessary for me to go into a detailed descrintion ci the method of building up the i'riction member and the specific operation thereof, since they are vvell lrnown to those skilled in the' art to which this invention pertains.

.ln the present showing, the arms 7 and 8 of the shock absorbing' device are connected to the upper and lower sections of the spring; fragments of which are shown in dotted lines at i3 and lil. As the attaching means are idcnticalin construction and operation l shall describe but one othem, it being undcrstood that this description. applies to both oi" those illustrated in the drawing. rlhe stud i.$ which may be made of steel or any material suitable 'for the purpose, is formed integral with or otherwise rigidly secured to a lyolre i6 which is clamped to the spring 1.3 and secured in position by the nut 17, as shown in dottedy lines in Fig. 1. This stud is provided intermediate of its ends with an enlarged annular portion 18 which abuts against the clamping member and forms a bearing' for the housing 3.9 which is preferably of the configuration clearly shown in Fig. 3, and is provided with a bore 20 for the reception of the free end of the stud l5, the housing 'being apable of arotary movement on said stud. in order to prevent play between the bore of the housing '19 and the stud l5, l have found it expedient to insert a bushing 2i. lllhen the housing is positioned on the stud as just described, it is held against the bearing surface of the en larged portion i9 by means ofthe castle nut 22 arlaiied to engage the threads 23 of the outer or ce ond of the stud. l5, a washer 2li being interposed between the outer face of the housing and the nut 22.v W hen the nut has been tightened up suliicicn'tly a Cotter pin 2d is employed in the usual manner to loch the same against Working loose by rea` son of the vibration and movement of the parte.

Below the bore 2O and extending at right angles thereto in the housing 19 is a second bore 25 for the reception of the stud member 26 terminating in an enlarged plate portion 27 adapted to loeriveted to or otherwise rigidly secured to the extremity of the arm 7, as shown at 28. This stud 26 similarly to the stud l5 is provided with an annular enlargement 29'or1ning a bearing surface for the contiguous portion of the housing;V 18. The bore 25 is provided with a bushing 30 to prevent vibratory movement of the 'stud 26 within the 'bore and the end of the stud 2G,y similarly to the stud l5, is threaded for the reception of 'the locking nut 3l, the housing being fastened in position on this stud in the same manner as that described in connection With the adjustment of the nut 22.

lt is obvious that by the construction of my `improved attaching means and the method of attaching the housing to the suspended parts and to the supporting arms, that the arms will not only be capable of' movement on an axis parallel to the axis of movement of the friction member 9 but on an axis at a right angle to the axis ot movement of said member 9, so that regardh-iss of the relative movements of the suspended parts of the vehicle, the arms 7 and 8 will always move in parallel planes thereby maintaining the entire contacting surfaces of the parts composing the friction member 9 in constant Working' contact.

By the employment of the bushings 2l and 30 any' Wear that might take place between the studs l5 and 26 and their bearings will be compensated for and a durable and eiiicient structure produced, ease of opera tion being further enhanced by the application of a suitable lubricant through the oil .cup 32 threaded into the op of the housing 19, as shown at 33.

As the arms 7 and 8 approach or recede from each other by the relative movements of the suspended parte, the housing 19 will rotate on the studs l5 and if during the movement there should be any tendency of the suspended parts to move in other than lli) parallel planes and develop what is com-
